Nearby Failed Stars May Harbor Planet

Pasadena, CA— Astronomers, including Carnegie’s Yuri Beletsky, took precise measurements of the closest pair of failed stars to the Sun, which suggest that the system harbors a third, planetary-mass object.The research is published as a letter to the editor in Astronomy &

New Survey Tools Unveil Two Celestial Explosions

Pasadena, CA—A team of researchers including Carnegie’s Mansi Kasliwal and John Mulchaey used a novel astronomical survey software system—the intermediate Palomar Transient Factory (iPTF)—to link a new stripped-envelope supernova, named iPTF13bvn, to the

Highest-ever Resolution Photos of the Night Sky

Pasadena, CA— A team of astronomers from three institutions has developed a new type of telescope camera that makes higher resolution images than ever before, the culmination of 20 years of effort.

High-energy astrophysics puzzle

Pasadena, CA— Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of a blazar known as PKS 1424+240 show that it is the most-distant known source of very high-energy gamma rays.

Astronomers Discover New Kind of Supernova

Pasadena, CA— Supernovae were always thought to occur in two main varieties. But a team of astronomers including Carnegie’s Wendy Freedman, Mark Phillips and Eric Persson is reporting the discovery of a new type of supernova called Type Iax.

Ancient, highly active galaxies discovered

Pasadena, CA — Using information gathered from several telescopes, a team of astronomers, including Carnegie’s Eric Murphy, searched the sky for very rarely seen dusty starburst galaxies, formed soon after the Big Bang.

Extremely Rare Triple Quasar Found

Pasadena, CA—For only the second time in history, a team of scientists--including Carnegie's Michele Fumagalli--have discovered an extremely rare triple quasar system. Their work is published by Monthly Notices of the Royal Astronomical Society.

Distance to nearest galaxy measured

Pasadena, CA— A team of astronomers including Carnegie’s Ian Thompson have managed to improve the measurement of the distance to our nearest neighbor galaxy and, in the process, refine an astronomical calculation that helps measure the expansion of the un
